What do you need to do with the system?

2. greenchild623

solve for x and y

3. eashmore

Is the system$\begin{matrix}-14 - 2 = y-7x \\ 2x = 10y + 4\end{matrix}$

4. eashmore

Do you have to use any particular method?

5. greenchild623

sorry.... it is: -14=-20y-7x 10y +4 = 2x

6. greenchild623

solve by elimination....

Weird. I replied to this but my answer isn't showing up. Let me re-type it real fast.

First, we need to solve the first equation for x. We get$x = -(20/7)y + 2$ Then we substitute this expression into the second equation. This yields $10y - 2(-(20/7)y + 2) = -4$Solve this for y and plug the value of y back into our expression for x. Let me know what you get.

x=34 y=?
